When [Dandu] noticed his Flower Power was no longer being detected by his iOS devices, he contacted support who told him that sadly this was a hardware failure and that he should just throw it away. But he had his doubts about this diagnosis as other devices such as his Raspberry Pi could still communicate with it. Upon closer inspection, he realized that the Flower Power didn’t have a name, and could only be contacted by its MAC address directly. Reasoning the lack of a name might be upsetting the “It Just Works” sensibility of his iGadget, [Dandu] started researching if there was some way to get the device to take a new name remotely.

Luckily for our hero, BLE is kind of broken. Searching for a solution to his problem brought him to a blog post by the creator of BLEAH which demonstrated exactly what [Dandu] was looking to do. Following along, it took only a single command to push a new name to the Flower Power’s BLE configuration. With that, his “broken” device was brought back to life. Why the device lost its name, or how to prevent it from happening in the future are questions for another day. [Dandu] will take the win.

If you’re interested in the popular new technology that’s compromising our security in the name of convenience and improved battery life, the rabbit hole starts here.

[bugloaf] tipped us off about this flower power hack. University of Washington researchers, [Babak], [Brian], and [Carlton] have developed very low power circuits to run directly off of trees. This builds upon the work of MIT researchers and Voltree Power. A voltage of up to around 200mV is generated between an electrode in a tree and an electrode in the ground. Identical metals can be used as electrodes as the process is not like that of a lemon or potato battery. The significant development here is the use of a boost converter and exceptionally low power circuits. What kind of applications can you come up with for this source of power? Maybe you could try to combine this power with the power from donuts and hair.
